The Reach Impact Institute (RII) was established with a purposeful and aggressive goal of significantly reducing overdose deaths in the U.S. and improving the lives of those struggling with addiction. The Institute strives to “de-escalate” the risk of fatal overdoses and establish lasting solutions that save lives and reach as many impacted individuals as possible.
We research, develop and deploy customized recovery-driven ecosystems that embrace the full continuum of services and resources needed to respond to overdoses, mental health crises, and long-term recovery needs.
We provide educational resources and validation from reputable subject matter experts, ensuring stakeholders have access to the latest evidence-based information.
We strengthen opioid abatement efforts and funding requests through strategic partnerships and data-driven approaches that maximize impact and save lives.
We incorporate voices of people with lived experience (PWLE) and people who use drugs (PWUD) to inform our work and help reduce stigma in communities.
At Reach Impact Institute, we believe that real progress can only be achieved through measurable results. We help communities track progress, identify gaps, and maximize investments - ensuring opioid abatement funds and other resources achieve measurable life-saving results.
